(Medical Xpress)—An enduring neurobiological mystery is why do vertebrate rods and cones shut down their transmitter release in response to a light stimulus. If that particular question is too broad, then consider a slight ...

Standard models of perception are stimulus-driven, meaning that the external perceptual event drives the brain's perception-related activity. However, the tide may be turning: recent ideas suggest that our perceptual experiences ...

Nystagmus is a genetically transmitted disease that causes an uncontrolled, back-and-forth twitching of the eyeball. Roughly one in every 1,500 men suffer from it. But before now, we did not know that this twitching is caused ...

(Medical Xpress)—It has long been held that in a new environment, visual adaptation should improve visual performance. However, evidence has contradicted this expectation: Adaptation sometimes not only decreases sensitivity ...

(PhysOrg.com) -- The brain is capable of holding and retrieving memories for specific fears, revealing a more sophisticated storage and recall capacity than previously thought, neuroscientists have found. The study, which ...
